The effect of dietary L-glycine (gly) on the growth and production of pupa and cocoon of the Nistari variety of silk worm Bombyx mori was investigated. Different treatment schedules (2% and 3% gly smeared on the mulberry leaves with once and twice supplementation from 1st and 2nd day of Vth instar larvae) were performed with suitable controls. The growth of the larvae and silk gland weight were significantly increased with gly supplementation. L-gly supplementation also enhanced the cocoon and pupa production. However, gly was found to have specific effects on the growth and production of pupa and cocoon of Bombyx mori.
